The customer was very worried. But we did not have the 26-inch roller cone bit in stock at the time. After asking the customer, we knew that the customer was in a hurry.

Therefore, we advice that the customer try the rock reamer instead of the tricone bit. We have the stock of the roller cone and we can produce it for him in 3-5 days. And after confirming the details of the rock reamer of following:

1. Both thread (6 5/8’’ API REG box-pilling eye)
